I am using module-native-protocol-tcp and module-tunnel-sink to stream audio from server A to server B. There are three wired home routers between A and B. All links are 100 base-t ethernet. Network traffic is light. CPU load is light. Both servers are running Ubuntu 20.04. Each server plays audio via its own USB DAC. There are no other known audio issues. I suspect network timing jitter is causing some TCP packets to arrive "late", causing the clicks and pops. There are no clicks or pops when I play music locally on A or B. What is the best way to diagnose suspected tunnel underflows? Is there a way to create (or increase the size of?) a buffer in the tunnel? I have considered trying RTP instead of native, but I have not done so yet. Thanks!
